Origin of PeptideNovel peptide for ocular delivery (POD)
Nature of Peptide/CargoA novel cell-penetrating peptide POD has the ability to penetrate and deliver fluorophores, siRNA, DNA and quantum dots to cells in culture and retinal and ocular tissues in vivo. It also acts as a microbicide, potentially providing a safer and more efficacious method of delivering molecules t
MechanismNovel peptide for ocular delivery (POD)
Cargo Sequence/StructureNone
Name of cargo
Not applicable
AssayFluorescence-activated cell sorting (FACS), Vital staining with Lissamine
EnhancerHER cells incubated with 2 nmol (8 μmol/l) L-POD for 15 minutes were treated with trypsin at 37 °C prior to counting of lissamine-positive cells by fluorescence-activated cell sorting (FACS)
Properties of enhancerNot mentioned
Concentration10 nmol of L-POD
Incubation time45 minutes
Tissue permeability (value with units)L-POD bound strongly to the cornea, sclera and the dura of the optic nerve in vivo. In contrast, lissamine only weakly stained the cornea and sclera and did not stain the dura of the optic nerve.
Tissue SampleCornea of male C57BL/6J mice
